The ui.DragDrop class is used to control the events related to drag & drop events.
When implementing drag & drop in a dialog, the ON DRAG* / ON DROP dialog control blocks take a ui.DragDrop variable as a parameter to let you configure and control the drag & drop events. The ui.DragDrop variable must be declared in the scope of the dialog implementing drag & drop.
